GeForce 940M vs GeForce GTX 260

Intro

Compare those specifications to the GeForce GTX 260, which comes with GPU core speed of 576 MHz, and 896 MB of GDDR3 RAM running at 999 MHz through a 448-bit bus. It also is comprised of 192 Stream Processors, 64 TAUs, and 28 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the GeForce GTX 260 should perform a lot faster than the GeForce 940M overall. (explain)

GeForce GTX 260		111888 MB/sec
GeForce 940M		16000 MB/sec
	Difference: 95888 (599%)

Texel Rate

The GeForce GTX 260 should be much (about 43%) more effective at AF than the GeForce 940M. (explain)

GeForce GTX 260		36864 Mtexels/sec
GeForce 940M		25728 Mtexels/sec
	Difference: 11136 (43%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 260 is superior to the GeForce 940M, and very much so. (explain)

GeForce GTX 260		16128 Mpixels/sec
GeForce 940M		8576 Mpixels/sec
	Difference: 7552 (88%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Price Comparison

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the interface width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
